Azodin kaos pump?

I have a phantom that I bought used on ebay (open class). I have to literally put my gun down against my leg to pump i all the way back. It feels like its grinding on metal and makes a horrible noise. I am 15 and not too strong, so I was seeing if my dad could. He also ended up having to put the tank on his thigh just to fully pump it back. I relubed the pump arm, the little guide groove, and all orings and springs. It didnt fix anything. This is my first phantom (and first pump) and I am pretty sure it is not supposed to be this way. I am sending it back to the seller and my dad really doesnt want me to buy used again and I dont think I want to either. Too many risks. So anyways, I was thinking about the azodin kaos pump. If I were to get one, I would get the black/gold with the single trigger frame and on/off asa- http://www.ansgear.c...CKGOLD&CartID=1 it also has a regulator. It seems like they fixed just about everything that was wrong with this one. So is it worth it? If not, do you guys have any other suggestions at around this price range new? Thanks in advance!
